WILLIAM DOUGLAS, OF TACOMA, WASHINGTON.

BOTTLE AND STOPPER THEREFOR.

To all whom it may concern:

Be it known that I, l/VILLIAM DOUGLAS, a citizen of the United States,residing at Tacoma, in the county of Pierce and State of Washington,have invented certain new and useful Improvements in Bottles andStoppers Therefor; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in bottles and stoppers therefor,and particularly to stoppers that are adapted to prevent or makeextremely hard the refilling of the bottle, without destroying thestopper or bottle.

Another object in view is the provision of a bottle and stopper thereforarranged to act in conjunction with each other for preventing orsubstantially preventing the refilling of the bottle without mutilatingor destroying the same or the stopper.

Another object in view is the provision of a bottle arranged forreceiving a stopper,

and means for holding the stopper against movement, the stopper beingadapted to freely permit the removal of the contents of the bottle, butto resist the forcing of liquid into the bottle.

A still further object of the invention is the provision of a bottlehaving a stopper provided with a plurality of tubes arranged withreciprocating valve members that permit the flowing in of liquid throughthe tubes when in a certain position, and prevent the flowing of liquidthrough the tubes when in any but that position, and a housing forprotecting sai'd tubes and preventing tampering therewith.

With these and other objects in view the invention comprises certainnovel constructions, combinations and arrangements of parts as will behereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a longitudina vertical sectionthrough the neck and part of a bottle and stopper constructed accordingto the present invention. Fig. 2 is a section similar to Fig. 1 showingthe relation of the aperture in the valve tubes to the lip in the neckof the bottle.

' Fig. 3 is a section similar to Fig. 1 except Specification of Letters.Patent.

Application filed May 18, 1908.

Patented Apr. 19, 1910.

Serial No. 433,530.

Referring to the drawing by numerals, 1 indicates a bottle of anydesired shape, and 2 the neck thereof, which may be of any desired shapeexteriorly, but its interior must be either preferably straight or widerat the top than at the bottom in order to permit the insertion of thestopper hereinafter more fully described. Formed in neck 2 is a groove 3that is adapted to receive a spring ring 1 which also engages a groove 5forined'in casing (3 of stopper 7. The ring 1 is adapted to be placed ingroove 5 and may be forced sufficiently therein to permit the insertionof the stopper 7 into the neck 2, and as the same is forced down untilgroove 5 comes even with groove 3, spring 4 will move over and fillgroove 3 and artially fill groove 5, that is, will ex 921ml in the usualmanner of a spring ring or engaging both grooves 3 and 5. This willprevent stopper 7 from being removed, unless the neck of the bottle isbroken. This will usually be sufficient for holding the stopper 7 inposition, but if desired I may provide the bottle 1 with a stop 8 uponwhich the stopper 7 may rest. The stop 8 is usually constructed in themanner of an offset or shoulder extending entirely around the neck 2 andusually there is placed a packing washer or ring 9 between the shoulderor stop 8 and the stopper 7 for forming a tight joint therebetween. Ifdesired the ring 4: may be dispensed with and stop 8 and the stopper 7held in by cement of any desired kind, though ordinarily the structurejust set forth is preferable.

Stopper 7 is formed with a housing 6 that is provided with a pluralityof apertures 10 near its upper end, and is adapted to engage or contactwith packing 9 at its lower end. Positioned in the upper third or upperpart of easing 6 at a reasonable distance below the apertures 10 is afilling 11 which may be made of cork, rubber or other desired material;and positioned in the lower part of easing 6 or the end opposite theapertures 10 is a second filling 11 which may be made of cork, cement orother material. These fillings are usually concave from below upward toform a well in their base. Positioned in the fillings 11" and 11 aretubes 12 and 13 that are adapted to form ways for the removal of liquidand the insertion of air. The tubes 12 and 13 are closed at the lowerend but are open at the upper end. Though open at the upper end they arerounded or bent over at 1 1 and 15 re spectively so as to constrict orreduce the end of the tube, to prevent the valve members 18 and 19 fromfalling out of the tubes 12 and 13. Tubes 12 and 13 are also formed withapertures 16 and 17 respectively. This is arranged so that air may enterin through some of the openings 10 and pass through the tube 12 and outopening 16 into chamber 21, then through tube 13 and finally out opening17 while liquid will pass through the same channels in the oppositedirection.

Positioned in tubes 12 and 13 are auxiliary tubes or valve members 18and 19 that are open at both ends, and are of such a size as to snuglyfit the inner bores of tubes 12 and 13. These valve members are adaptedto reciprocate freely in tubes 12 and 13 in order to open or closeapertures 16 and 17, the apertures 16 and 17 being held closed by thesevalve members when the bottle is set in an upright position or held insubstantially that position, but when the bottle is turned over orupside down valve members 18 and 19 are moved from covering openings 16and 17 until they contact with the restricted or bent over portions 14:and 15. This will permit liquid to pass from opening 17, tube 13, valvemember 19, through chamber 21 and thence through opening 16, and fromthence out some of the openings 10. These valve members should be ofsuch size and weight as will be sufficient to insure their movements.Valve members 18 and 19 are adapted to extend nearly the full length oftheir respective tubes 12 and 13 so that a very slight movement vthereofwill cover the various apertures 16 and 17. The action of these valvemembers in closing the apertures and preventing the entrance of waterdepends on the contact of their lower outer circumference against theangle of the floor of the containing tubes, consequently it is essentialthat these valve members have a regular outline at their bases and thatthe tube floor be distinctly angular, not flat in relation to the wallof the tube. Water tends to enter the closed valve at the lower end ofthe valve members and air to make its entrance via the upper marginbetween the tube and the valve members. By reason of the restrictedportions lt and 15 not only will the valve members 18 and 19 beprevented from moving out of their respective tubes but an instrumentwill be prevented from removing the same. The housing 6 is also adaptedto prevent any use of tools in removing valve members 12 and 13.

The stopper 7 is adapted to be fitted into the lower end of neck 2 sothat a cork or stopper 20 may be used if desired, although it will beevident that stopper 7 could be 7 positioned so that the upper end ofcasing 6 would be flush with the top of neck 2.

The space between fillings 11 and 11" in stopper 7 designated'chamber 21takes the place of a reservoir and acts as an inverted unspilling inkwell. chamber is acquired by the disposition and size of the tubes, theupper valve tube 12 being usually of larger or not less diameter thanthe lower tube 13 and this upper tube 12 protrudes not farther into thechamber 21 than is necessary to clear the upper margin of the aperture16 in its wall. The lower tube 13 protrudes upward through the filling11 to a distance not less than one half the diameter of the inside ofthat part of the stopper 7 contained in chamber 21 and the aperture 17protrudes into the bottle cavity proper, the upper margin of aperture 17being on a level with the lower margin of filling 11, to permit theescape of all fluid contents. The action of this chamber in preventingthe inflow of liquids from without lies in the fact that liquid only canenter the chamber 21 while the valve member 18 is moved away from theaperture 16 and while the aperture 16 is facing downward consequentlywhen a sufficient quantity 0 7 liquid has entered the chamber by refluxthrough valve tube 12 the aperture 16 becomes submerged and no moreliquid can enter and the amount of liquid that has entered up to thesubmerging point of aperture 16 is insuiiicient under the disposition ofthe parts to reach the entrance 14 of tube 13 either in the horizontalor any other position, consequently no liquid can flow into tube 13.Should the liquid in chamber 21 be shaken into tube 13 the valve actionprevents any escape into the bottle and any eiiort to open the valve intube 13 removes the liquid back into chamber 21.

It is noticed that the escape of liquid in emptying the bottle providedwith this device, is more free when the apertures 16 and 17 are in thesame direction, consequently to aidin the ready removal of liquid inemptying the bottle it is usual to have some mark such as a lip 22 orelongation of the mark in the neck '2 of the bottle, this lip orelongation being in the oppositeside to the apertures 16 and 17 WVhat Iclaim is:

1. In a device of the class described, a bottle formed with a neckportion, a housing This action of the fixed in the neck portion,fillings arranged tion and to expose the said openings when the bottleis inverted.
